Application filed l'une 28, 1909. Serial No. 504,835.

To all whom it may concern:

Be it known that I, GEORGE W. BERN- AUER, a citizen of the UnitedStates, residing at St. Charles, in the county of St.

Charles and State of Missouri, have invented a new and usefulFlue-Blower, of-

which the following is a specification.

The object of the invention is to afford a simple, effective and durabledevice for steam or air-cleaning boiler fines, which may be easilyplaced in operative position and which overcomes dificulties which aresometimes advanced against devices of similar general character. Thesedesideratums are attained by the features of construction describedhereafter in detail and illustrated in the accompanying drawing, inwhich Figure 1 is a detached perspective of the device, the partsassembled and the whole ready to be placed in operative position;

. Fig. 2 illustrates the invention in operative position relative to therear head of a boiler; Fig. 3 is an enlarged sectional view t irough thelongitudinal axis of the double-seated swivel joint and its pedestal;Fig. at an enlarged front elevation of said doubleseated swivel jointand said pedestal, and Fig. 5- a side elevation illustrating theposition of thenozzle relative to the boiler-head while.

the device is in operation.

Like numerals refer to like parts throughout the several views, numeral1 designating the steam or pressure fluid suppiy pipe 11 on which arelocated, where desirable, va ves 2 and 3, serving, respectively, asmeans to drain said supply pipe of condensation and as means to controlthe entrance of steam, compressed air or other fluid into the partsleading to the nozzle. A cock 4 which may be supplanted by other form oivalve, may serve the useful purpose of draining the pipes andattachments between said valve 3 and nozzle 5, thereby insuring that nomoisture will be thrownfrom said nozzle into the boiler flues. threadedapertures 7, is loosely mounted upon pipe 8 and serves, when saidthreads are engaged by screws 9, as a support for a part of saiddouble-seated swivel omt. Said joint comprises the peculiar and originalfeatures of construction shown in Fi s. 3 and 4:, in which numeral 10designates the lower and 11 the upper member, seats being indicated at12 and 13 upon which packing or washers may be placed to form a steam orair-tight compartment. The pipes upon A pedestal 6, havingwhich saidjoint is illustrated imposed may terminate, approximately, at a pointcoincident with the horizontal plane of seats 12 and l3, and a smallcompartment or space, as indicated at 14 and 15, would thus existbetween the ends of said pipes, but said detail is not held to bematerial as to exactness and the distance between the ends of said pipesand the consequent depth of said compartments, 14, 15, may be varied asfound expedient. Member 11 of said joint is surmounted by a heavy foot16 serving as a bearing surface for screws 9 which pass freely throughsmooth bored apertures therein, and run in grooves 17 provided upon theexternal face of member 11. Surmount' pipe section 18 is an adjustableband 19 provided with a'lever 20, and upon the ex-- ternal circumferenceof said band are notches 21. a foot 22 projecting from a resilientpointer 23 tripping therein. Beneath each 0 said notches numerals may beengraved corresponding to the series of flues, by which the preciselocation of nozzle 5 with reference to said lines may be at all timesapparent; likewise the sharp metallic click produced by the suddenengagement of said. resilient pointer with said notches enables theoperator to locate said nozzle precisely opposite any series of flues hemay have reason to believe are especially in need of blowing, saidmetallic click obviously enabling him to halt said nozzle before eachtier of fines with exactitude and without an examination of theaforementioned engraved numerals. A compartment of metal or othersuitable material comprising plates 24, the top, 25, the sides, and 26,the base, is provided to rest substantially within the boilerhousing-27. Said compartment is provided with a movable gate 28, havinga half-e e 29 tostraddlc and Lock in position nozz e-pipe 30, and alifting lug 81, and within said housing works a detachableand adjustablemember, preferably a roller and roller-socket, 32, 33, a set-screw 34being indicated. Nozzle 5 is provided with suitable apertures 35 throughwhich the pressure fluid is projected lnto each of the boiler fiues. 1,said nozzle is seen in repose and locked by half-eye 29 close againstthe inner wall 36 of theboiler housing 27 and in juxtaposition to the.corner or angle 37, formed by the juncture of the rear wall and a sidewall of said housing, where 'it is out of the path Referring to Fig.

of the flames and least liable to damage, while in Fig. 5 it will benoted that said nozzle approaches very close to the boiler fluesinsuring that the steam thrown therein will be dry and subject to noappreciable condensation.

It should be noted that when, in operating the device, lever 20 is swungfrom right to left it does not encounter index or pointer 23 as whensaid lever is ad'acent said pointer the nozzle has complete the extentof its sweep and rests at, approximately, point 86 in Fig. 2. Gate 28serves a threefold purpose: to look, by its eye 29, said nozzle intoposition; to afford a clear view of the interior of the combustionchamber, of the boiler-head and. of the action, eilicacy and conditionof said nozzle; and to permit a cyclone draft to enter and assist inforcing the jets of steam swirling at high velocity through the fines. Aplurality of eyes 29 may be disposed in gate 28, so that the nozzle maybe locked in any desired position.

Though the preferred form of the device is herein described, the rightis reserved of making such change in the size, arrangement andconstruction of the various parts as may, from time to time, proveexpedient or desirable and without departing from the scope and spiritof my invention.
